Information sources forms the basic stock for the services to be provided by
libraries and information centers. Systematic organization of information
sources and or their surrogates is essential for effective retrieval. The
document surrogates along with author and title are also prepared and arranged
under the name of the subject, Terms (vocabularies) are used to represent the
subject name in the surrogate entries. To represent subjects, objectively
irrespective of space and time the vocabulary used must be controlled. thesaurus
is a prime vocabulary control tool. The natural language i. e. vocabulary used
in ordinary discourse can also be used for representation subjects in
information storage and retrieval systems. However, the richness of natural
language in word forms and variety affects the recall and precision precision
performance of ISRS.So to have the expected level of recall and precision
controlled vocabulary is essential. The synonyms in natural language scatter
entries of documents on the same subject under different names. The homonyms
need to be controlled to avoid retrieval of irrelevant information. Singulars
and plurals if not controlled may also retrieve irrelevant information. Whereas,
uncontrolled coordination of term result in retrieving unwanted information. and
missing some relevant information. A thesaurus as a vocabulary control
tool provides solutions to all these problems posed by the natural language in
information storage and and retrieval. The library and information science is
one of the fast developing interdisciplinary subject. Literature on this subject
ins increasing at exponential rate. For effective storage and retrieval of
information on LIS either in hard copy format or in digital format, offline as
well online, vocabulary control tool like a thesaurus was urgently needed.
To fulfill this need the present thesaurus is constructed. this is the first and
only thesaurus on this subject, so far constructed in India. This is unique
thesaurus as it is constructed gy adopting the blending of the two approaches i.
e. a priori and posteriori approach. Further, the thesaurus is based on a
specially constructed speculator based depth classification schedule of LIS
terms. Apart from the thesaurus the books also contains the depth
classification schedule of LID. It also explains in detail the
methodologies adopted in the construction of the depth classification schedule
as well as the thesaurus of LIS terms. The book is divided into six
chapters. First chapter describes the uses of thesaurus . Second chapter
explains various concepts dealing with depth classification. It also reviews
literature dealing with depth classification. definitional analysis of
